From e0d1a3f01bf19312b4dc3d4404f57e6bd5907fec Mon Sep 17 00:00:00 2001 From: Zhexuan Yang Date: Sun, 8 Feb 2026 19:47:25 +0800 Subject: [PATCH 1/6] fix(s3): include port in Host header for non-standard ports Fixes SigV4 signature mismatch when connecting to S3-compatible services (e.g., MinIO) on non-standard ports. The signer now includes the port in the Host header when explicitly specified in the URI, matching what reqwest sends in the actual request. Previously, uri.host() returned only the hostname without port, but reqwest sends "host:port" for non-standard ports, causing signature verification to fail with 403 Forbidden. --- src/io/s3/signer.rs | 76 +++++++++++++++++++++++++++++++++------------ 1 file changed, 57 insertions(+), 19 deletions(-) diff --git a/src/io/s3/signer.rs b/src/io/s3/signer.rs index 871f547..74fb382 100644 --- a/src/io/s3/signer.rs +++ b/src/io/s3/signer.rs @@ -8,23 +8,6 @@ use crate::io::s3::config::AwsCredentials; use http::{HeaderMap, HeaderValue, Method, Uri}; use std::time::{SystemTime, UNIX_EPOCH}; -/// Sign an HTTP request with AWS `SigV4`. -/// -/// This function adds the necessary AWS Signature Version 4 headers to authenticate -/// requests to AWS S3 or compatible services. -/// -/// # Arguments -/// -/// * `credentials` - AWS credentials (access key ID, secret access key, optional token) -/// * `region` - AWS region (e.g., "us-east-1") -/// * `service` - AWS service name (typically "s3") -/// * `method` - HTTP method -/// * `uri` - Request URI -/// * `headers` - Existing request headers (will be modified in-place) -/// -/// # Returns -/// -/// Ok(()) if signing succeeded, Err otherwise. pub fn sign_request( credentials: &AwsCredentials, region: &str, @@ -48,8 +31,19 @@ pub fn sign_request( let amz_date = format_amz_date(now.as_secs()); let date_stamp = &amz_date[..8]; - // Extract host from URI - let host = uri.host().ok_or("Invalid URI: missing host")?.to_string(); + // Extract host from URI - include port for non-standard ports + // This matches what reqwest sends: host:port for non-standard ports + let host = if let Some(port) = uri.port_u16() { + // Include port if explicitly specified (e.g., 127.0.0.1:9000) + format!( + "{}:{}", + uri.host().ok_or("Invalid URI: missing host")?, + port + ) + } else { + // For implicit ports (443 for https, 80 for http), use host only + uri.host().ok_or("Invalid URI: missing host")?.to_string() + }; // Build the path and query string let path = uri.path(); @@ -399,6 +393,50 @@ mod tests { assert!(canonical.contains("x-amz-date:20250101T000000Z\n")); } + #[test] + fn test_sign_request_with_non_standard_port() { + let creds = AwsCredentials::new( + "AKIAIOSFODNN7EXAMPLE", + "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY", + ) + .unwrap(); + + // Test with explicit port 9000 (common for MinIO) + let uri = Uri::from_str("https://127.0.0.1:9000/bucket/key").unwrap(); + let mut headers = HeaderMap::new(); + + let result = sign_request(&creds, "us-east-1", "s3", &Method::GET, &uri, &mut headers); + assert!(result.is_ok()); + + // Host header should include the port + let host = headers.get("Host").unwrap().to_str().unwrap(); + assert_eq!(host, "127.0.0.1:9000"); + + // The canonical headers should also include the port + let auth = headers.get("Authorization").unwrap().to_str().unwrap(); + assert!(auth.contains("AKIAIOSFODNN7EXAMPLE")); + } + + #[test] + fn test_sign_request_with_standard_port() { + let creds = AwsCredentials::new( + "AKIAIOSFODNN7EXAMPLE", + "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY", + ) + .unwrap(); + + // Test with standard HTTPS port (no explicit port in URI) + let uri = Uri::from_str("https://examplebucket.s3.amazonaws.com/test.txt").unwrap(); + let mut headers = HeaderMap::new(); + + let result = sign_request(&creds, "us-east-1", "s3", &Method::GET, &uri, &mut headers); + assert!(result.is_ok()); + + // Host header should NOT include port for implicit standard ports + let host = headers.get("Host").unwrap().to_str().unwrap(); + assert_eq!(host, "examplebucket.s3.amazonaws.com"); + } + #[test] fn test_format_canonical_headers_with_session_token() { let mut headers = HeaderMap::new(); From 04766ac7285e92ae15fcd2c3ec0166e946ace632 Mon Sep 17 00:00:00 2001 From: Zhexuan Yang Date: Sun, 8 Feb 2026 20:02:44 +0800 Subject: [PATCH 2/6] fix(s3): correct SigV4 canonical request per AWS spec Three issues in the SigV4 signer: 1. Missing payload hash: The canonical request had 5 components but AWS SigV4 requires 6. The HexEncode(Hash(Payload)) was missing as the final component, causing signature mismatches with all S3- compatible services. 2. Query string in canonical URI: The URI query string was appended to the canonical URI field. Per the spec, the canonical URI must contain only the URL-encoded path; the query string belongs in the separate canonical query string field. 3. Missing blank line separator: The format string omitted the '\n' between canonical headers and signed headers, which (combined with canonical headers' trailing '\n') produces the required blank line separator per the AWS spec. Also adds comprehensive tests covering: - Canonical request structure (6-component validation) - Query string separation from URI path - Payload hash presence - Deterministic signing with fixed timestamps - MinIO path-style URL signing - Host:port for non-standard ports Co-authored-by: Cursor --- src/io/s3/signer.rs | 698 ++++++++++++++++++++++++++++++++++++-------- 1 file changed, 570 insertions(+), 128 deletions(-) diff --git a/src/io/s3/signer.rs b/src/io/s3/signer.rs index 74fb382..ccd35a2 100644 --- a/src/io/s3/signer.rs +++ b/src/io/s3/signer.rs @@ -15,6 +15,30 @@ pub fn sign_request( method: &Method, uri: &Uri, headers: &mut HeaderMap, +) -> Result<(), Box> { + let now = SystemTime::now() + .duration_since(UNIX_EPOCH) + .map_err(|_| "System time is before UNIX epoch")?;

In ROS1 bag files, OP_CHUNK records contain the actual compressed/uncompressed message data (OP_MSG_DATA and OP_CONNECTION records). This fix adds: - decompress_chunk(): handles none/lz4/bz2 compression formats - parse_inner_records(): extracts message data and connection records from decompressed chunk payloads - Updated channel cache rebuilding to detect new connections from chunks - 22 new tests covering decompression (all formats, error cases), inner record parsing, end-to-end chunk processing, incremental streaming, and the StreamingParser trait integration - Fix clippy needless_borrow warning in signer.rs Co-authored-by: Cursor --- src/io/formats/bag/stream.rs | 639 ++++++++++++++++++++++++++++++++++- src/io/s3/signer.rs | 2 +- 2 files changed, 637 insertions(+), 4 deletions(-) diff --git a/src/io/formats/bag/stream.rs b/src/io/formats/bag/stream.rs index 29f547e..cbcd5ee 100644 --- a/src/io/formats/bag/stream.rs +++ b/src/io/formats/bag/stream.rs @@ -362,8 +362,15 @@ impl StreamingBagParser { self.connections.insert(conn.conn_id, conn);
